Precision Planting Products

If I remember correctly, there was a small thread on these components not to long ago, but can't remember. I was thinking they didn't offer much improvement on CIH factory setups. If anyone has an experience on these products, are they worth the money? Not even sure if I can improve on my CIH 1200, but I'm always open to new technology that offers improved results. I've got a local crop consultant that is now a dealer for them and I know it's only a matter of time before he contacts me with his sales pitch. I was wanting to have at least some type of baseline knowledge of what they offer, but don't see much for the CIH line.
